You are in a tough predicament. I looked for 7 years for nice used and NOS woodgrain parts for my 70 Charger R/T....finally gave up. Whether used or NOS I was not match able to match up a nice looking set. Ended up sending a complete set of original used to Instrument Specialties for resto. They came out very nice....not exactly OEM in appearance but the best I have seen to date.
Here is an Ebay link to the resto service:
